Dstat helps you figure out why your computer is running slow
|
Conclusion
The all-around tool dstat offers many options for taking a look into all areas of a system. As soon as a computer slows down, you can easily identify where the resources are being consumed via a quick invocation of dstat. The numerous modules also offer the possibility for gathering metrics on various applications, which can be especially interesting for server administrators.
Because dstat is implemented in Python, many measurements are susceptible to a minimal deviation. After all, dstat itself consumes resources. The dstat manpage has good instructions for how to determine the resource usage of dstat itself.
